We develop and manufacture special seals for power stations, for the chemical and petrochemical industries, for machinery and pipeline construction. In other words, seals that provide the greatest possible reliability even under extreme operating conditions (pressure, heat, cold, aggressive media) – at temperatures from -200 to +1.000 °C. Product Range: - DVGW tested, see separate brochure - Punched, cut seals - Plates, foils - Semi-finished items - Form articles Benefits: - Highest chemical resistance - Insoluble and does not swell in organic or anorganic solvents - Resistant to the weather - Temperature range -190 to +250 °C - Highly anti-adhesive, does not stick - Resistant to hydrolysis Common fillers: - Quartz - Glass - Carbon / Graphite - Bronze - or without filters Fillers reduce the cold flow, lead to higher resistance to temperature and media, improve thermal conductivity and increase resistance to abrasion and pressure levels.

Due to the wide range of different designs, perfectly suitable PTFE seals are available for every application. The PTFE gaskets from billi are characterized by high dielectric strength, excellent electrical insulation properties and a low thermal conductivity. All items are manufactured with a high processing quality. Discover the various PTFE gaskets in our online catalogue and order the right products for your application directly from billi. Depending on the respective requirements, different PTFE seals are suitable for you: Our comprehensive range includes, for example, PTFE thread sealing tapes with a temperature resistance of -200°C up to +260°C. The PTFE tapes are both, odourless and insoluble. In addition, the PTFE thread sealing tapes have a particularly low coefficient of friction, which improves their performances. We also offer PTFE cord with a pressure resistance of up to 10 bar. Possible applications include valves as well as piston and centrifugal pumps.

Closures, more commonly known as shields and seals are used to protect the internal parts of the bearing against dust, liquid, and gaseous particle contamination. The shields help contain the lubricant in the bearing but are not designed to keep out liquid and gaseous contamination. We manufacture our own shields at WIB to the precise tolerance to minimize the opening gap, thereby offering great grease retention and longer life. On the other hand, seals are designed to keep various types of contamination out, keeping the grease clear of foreign particles and extending the bearing life.
